To all whom it may concern:

Be it known that I, HYMAN ELI Gouinnc, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a specification.

The object of my invention is an improved totalizer, adapted to be used in a manner similar to the totalizerV Vshown in Patent No. 893,719, issued to John C. Wahl, July 21, 1908.

The main object of my invention is a totalizer which calculates for both addition and subtraction, and which contains its parts rigidly supported, and 1s of easy and cheap manufacture. i

The mechanism is illustrated in the drawings, of whichation of the figure keys of the typewriter produces a rotation in the master wheel, which rotation is transmitted int-o the carrier wheels of the totalizer. The master dog serves to operate the parts of the totalizer,

articularly to disconnect the carrier wheel i of the'totalizer which is ,being operated by the master wheel from the next lower carrier wheel,-that is, the carrier wheel to the right. More in detail, the operation of the parts is timed as follows: At the beginning of the depression of a figure key the master mechanism operates the master dog. Mean-- while, the master wheel has been held stationary. The continuation of the depression of the gurelkey brings the master dog to rest and then begins the rotation of the master wheel thus rotating the carrier wheel engaged thereby. The master wheel is then brought to rest and locked in position, and after such bringing to rest, the master dog is retracted to its prior or normal position. All these movements occur during the down stroke of the figure key. Upon the upstroke .of the key the typewriter carriage and totalizer move one step to the left, moving the carrier wheel'which is in engagement With the master wheel out of engagement therewith and bringing the carrier wheel immediately to the right into engagement therewith. This completes the cycle of operations. This has been thoroughly described in great detail in the above cited patent and reference is made toit for a'more extended description of the parts.

Referring now to the drawings, 8 'represents the master wheel and 10 the master dog.. The normal condition of the master dog its with its upper end to the back, that 1s, with the upper end to the right, looking at Fig. 1. The totali'zer is composed of the side walls 11, 11,- which support the numeral wheel shaft 12, the intermediate wheel shaft 13, the carrier wheel shaft 14, the carried pinion shaft 15, theppawlshaft 16 and the locking plate 17 which serve to support` thirty-toothed disk 241 has two functions,

namely: (1) to be engaged and driven by the master wheel 8, as above explained, and (2) to be engaged and driven by the carried pinion 25, as will be explained below. The three-scalloped disk 242 has one function, namely, to lock the pawl 26 at all times eX- cept during the period of carrying The three-toothed gear 248 has one function, namely, to drive the carried pinion 25 during the carrying. Each carried pinion 25 is a plain spur gear with its hubs 251 somewhat beveled. Its functions are: First, it is an intermediate pinion between one carrier wheel and the next carrier wheel to the left, for the purpose of carrying tens, asis well known in the' art. Second, it serves as a lockable member to be lcke'd by the pawl 26 to prevent the 'overthrow in carrying. Third, italso serves as lockvable member in another manner to be locked by the lock plate y17 to help to .keep the parts alined. Each pawl 26 is composed of two parts, 261 and 262. The function of 261 isto lock the coperating carried pinion 25, which is so locked whenever the pawl end 261 is squeezed in between the teeth of the pinion. Again, reversely, if the pinion be rotatedv thepawl end 261 is forced away from said pinion and the pawl end 262 is therefore forced toward and into the threescalloped disk 242. Should a carrier wheel be rotated, as by the master wheel or in carrying, then as long as its three-scalrotatesit, thus tending to force its coperating pawl end 261 away and the pawl end 262 in toward the three-scalloped disk 242,-

then at that. time such tendency will not be.

interfered .with because the scallop of the three-scalloped disk will simultaneously present itself opposite the pawl end. Fig. 1 represents the parts in such position. Upon the continuation of the rotation of the carrier wheel, the scallop passes by and the cy-` lindrical surface again forces the pawl end 262 away and thus again locks its carried pinion 25 and its engaged carrier wheel 24 next to the left.

The above explains how the actual carrying and the locking during the` carrying take place. It shows that each carrier wheel is located against overthrow. Were the mechanism intendedas a counting mechanism, the parts mentioned would be sulicient.. But it is intended as a totalizer, as distinguished from a counting mechanism, and it is therefore necessary to have one more function, namely, the possibilityof operating any carrier wheel independently of the carrierwheel to the right, andit is therefore necessary to show how this additional function is accomplished.

Referring particularly to Fig. 2, it will be seen that the number of carried pinions is one less than the number of carrier wheels 24. Thetotal width of a carried pinion is made equal to the width of a carrier wheel, and it is therefore evident lthat this leaves some room to spare upon the carried pinion shaft 15. The carried pinions can therefore be slid upon their shaft, some to the right, the rest to the left, and they are so slid by the knife edge top 101 of the master dog 10, which enters between thecarried pinions and forces them apart, taking up all the spare room between them. The carried disks at the left are thus pushed into their proper positions to operate in the manner above described. Now the master dog and master wheel are so located that the master dog upon its operation forces to the right all the carried pinions to the right of it, inclusive of the one normally locking the carrier wheel which is .just now engaged by the master wheel. Said carrier wheel is thus disconnected from the carrier wheels to its right and can therefore be rotated independently of them. This is the additional function above mentioned as being required to distinguish a totalizer from a counting mechanism.

The carried pinions forced to the right do not have any force exercised on them tending to turn them, but they might nevertheless be turned by the jarring and vibration in the machine. Therefore, to help keep vthem alined and to help eliminate 10st motion, Ithe lock plate 17 is provided. Tt is comb-shaped and its teeth are so shaped as to be engagedby the carried disks in the position at the right. This plate is not necessary for the operation of the machine, but is simply-a convenience.

In Fig. 3 is shown a modification of the above mechanism. The three-scalloped piece 242 at the middle of the carrier wheel has had its diameter increased until it finally has become equal to that of the thirtytoothed gear 241. 1f left unaltered, it would .have interfered with the teeth of the master wheel 8 and the carried pinions 25. Tn order not to interfere, it has had spaces cut in it inv alinement with the spaces cut in the thirty-toothed gear andit has thus become a thirty-toothed gear with three teeth removed, namely, those opposite the three teeth of 243. The scallops upon the threescalloped piece now assume a different shape and a corresponding change must be made upon-the pawl end 262, as shown in Fig. 3. Here the end 262 normally rides upon the top of the teeth 242, being too wide to drop into the spaces thereof; but at the places where the teeth have been cut away, that is, at the places corresponding to the scallops, the space is wide enough and the pawl end 262 drops down in a manner similar to that above described.

The drawings and the above specification show a totalizer wherein the carrier wheels are mounted so as not to be separable into two groups by being movefd axially while the-carried intermediate pinions are capable ofbeing so moved. Without departing from the spirit of my invention, the above construction could be reversed. The carried pinions might be mounted so as to be axially non-movable, while the carrier wheels might be moved axially in one direction to make and in the other direction to break the concarried pinions to coperate with them, and

means for moving any or all of the wheels of the totalizer in an axial direction to thereby split the set of wheels into two groups so group and the lowest carrier wheel 'of the.

higher group shall be disengaged from each other.
